DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a stainproof treatment agent. More particularly, the present invention relates to a stainproof treatment agent comprising a specific copolymer having a fluoroalkyl group and a specific blending copolymer. The stainproof treatment agent of the present invention is particularly useful for a carpet.
RELATED ART
In order to impart the water repellency, oil repellency and stainproof properties to textiles (e.g. carpet), various stainproof treatment agents have hitherto been suggested. Japanese Patent Kokoku Publication Nos. 17109/1988, 55515/1991 and 55516/1991 disclose that a stainproof treatment agent comprising a urethane compound and a specific blending copolymer imparts the water repellency, oil repellency and stainproof properties. However, according to these copolymers, the water repellency, oil repellency and stainproof properties after cleaning are insufficient.
Japanese Patent Kokai Publication No. 59277/1983 also discloses a water- and oil-repellent agent comprising a copolymer containing vinyl chloride. The water repellency and oil repellency before and after cleaning are almost the same but the stainproof properties are insufficient.
Japanese Patent Kokoku Publication No. 28147/1989 discloses a composition for treating a carpet, comprising an adipate ester (low molecular weight) and a blending component. However, this composition can not impart sufficient water repellency, oil repellency and stainproof properties after cleaning.
None of stainproof treatment agents, which have hitherto been proposed, can have sufficient water- and oil-repellency as well as stainproof properties before and after cleaning.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a stainproof treatment agent having durability capable of maintaining sufficient water- and oil-repellency and stainproof properties before and after cleaning.
The present invention provides a stainproof treatment agent comprising:
DETAILED DESCRIPTION OF THE INVENTION
The repeating unit (I) is preferably a repeating unit derived from (meth)acrylate having a fluoroalkyl group. The monomer constituting the repeating unit (I) is preferably one represented by the general formula: carbon atoms; a --SO.sub.2 N(R.sup.3)R.sup.4 -- group or a --CH.sub.2 CH(OR.sup.5)CH.sub.2 -- group (R.sup.3 is an alkyl group having 1 to 10 carbon atoms; R.sup.4 is a linear or branched alkylene group having 1 to 10 carbon atoms; and R5 is a hydrogen atom or an acyl group having 1 to 10 carbon atoms); and
Examples of the monomer include the followings: OCOC(CH.sub.3).dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2, OCOCH.dbd.CH.sub.2, OCOCH.dbd.CH.sub.2, OCOC(CH.sub.3).dbd.CH.sub.2 and OCOCH.dbd.CH.sub.2, but are not limited thereto.
The repeating unit (II) is preferably derived from a vinyl monomer containing no fluorine. Examples of the preferable monomer constituting the repeating unit (II) include ethylene, vinyl acetate, halogenated vinylidene, acrylonitrile, styrene, alkyl (meth)acrylate, polyethylene glycol (meth)acrylate, polypropylene glycol (meth)acrylate, methoxypolyethylene glycol (meth)acrylate, methoxypolypropylene glycol (meth)acrylate, vinyl alkyl ether and isoprene, but are not limited thereto.
The monomer constituting the repeating unit (II) may be a (meth)acrylate ester having an alkyl group. The number of carbon atoms of the alkyl group may be from 1 to 30, e.g. from 6 to 30, specifically from 10 to 30. For example, the monomer constituting the repeating unit (II) may be acrylate esters represented by the general formula: alkyl group represented by C.sub.n H.sub.2n+1 (n=1-30). By copolymerizing these monomers, the water- and oil-repellency and stainproof properties as well as various characteristics (e.g. cleaning resistance, washing resistance and wear resistance of these properties, solubility in solvent, hardness and feeling) can be improved according to ne
